TO CONTINENTAL CAN COMPANY,INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK EASY OPENINGCONTAINER Application filed January 10, 1931.

The invention relates to new and useful improvements in easy openingcontainers, and more particularly to the features of construction thathave to do with the reclosure of E the container after the end or coverhas been released by tearing away a rip strip.

An object of the invention is to provide a container wherein a reclosurecollar is formed by a folding of the body wall, which reclosure collaris rigidly attached to and depends from the end after it is released bytearing away the rip strip, and wherein said fold forming the reclosurecollar is so disposed that the body wall may be provided with the usualflange for connection to the end by double seaming.

In the drawing Figure 1 is a vertical sectional view showing a containerembodying the invention.

Figure 2 is an enlarged sectional View through the upper end of thecontainer before the rip strip has been removed.

Figure 3 is a view showing the rip strip removed and the end lifted fromthe container body.

Figure 4 is a view in section on an enlarged scale through the coverflange before it is joined to the container body.

The invention is directed to an easy open- 59 ing container wherein thebody portion is provided with score lines spaced from each other andarranged adjacent the upper end of the container, thus forming a ripstrip which may be torn away for releasing the end from the container.l/Vithin the container body is preferably arranged a reelosure collarwhich is secured to the container body and which projects upwardly abovethe lower score line so that the upper edge of the collar, when the 49rip strip is torn away, forms the upper edge of the container body. Thepresent invention has to do particularly with the forming of a reclosurecollar which is attached to the end after it is released for the purposeof cooperating with the inserted collar attached to the body forreclosing the container. This collar which is attached to the end isformed from the body wall of the container. The body wall is foldedwhile in the blank so as to provide an inwardly and downwardly ex-Serial No. 507,956.

tending folded portion which depends below the upper score line. Thebody wall is folded upwardly at the lower end of said depending portion,and the upwardly extending portion projects above the fold in the bodywall so as as to provide a flange and a portion which may be attached tothe end by double seaming.

Referring more in detail to the drawing the invention is shown asapplied to a container which includes a body portion 1 to to which anend 2 is secured by a double seam The body wall is provided with aninwardly projecting bead 4 and with an inwardly projecting portion 5which provides a shoulder 6. Inserted within the can body, after it chas been shaped into cylindrical form, is a reclosure collar 7. Saidcollar is provided with a series of lugs 8 struck up from the collar andbent outwardly so that when the collar is placed in the container bodythe {c lower edge of the collar rests on the upper wall of the bead 4,and the lugs 8 will spring behind the shoulder 6 and thus firmly holdthe inserted collar in place. The body wall is provided with a scoreline 9 and also a i score line 10. Between the score line is a rip strip11 to which a key may be attached for winding the rip strip onto the keyand rupturing the body on the score lines, thus releasing the end fromthe container body.

The body wall of the container is folded back upon itself as indicatedat 12. The upper fold is indicated at 13. This inwardly and downwardlyfolded portion 12 lies flat against the inner face of the body wall. Theinwardly folded part is again folded at 14 upwardly so that it extendswell above the fold 13. This provides a depending collar formed from thebody wall, which depending v collar extends below the upper score line10. it? The inserted collar 7 is of such diameter that the dependingvcollar 12 extends downwardly outside of the collar 7. The body wallprojecting above the fold 13 is flanged in the usual way, and thisflange is rolled into a double seam 15 which connects the body to theupper end 16.

The depending portion 12 makes contact with the inner face of the outerwall of the container body, in the region directly below the upper scoreline. The inserted collar 7 makes contact with the inner face of thewall of the container body in the region directly above the score line9. hen the rip strip is being torn away it will be rolled along a solidfoundation consisting of the inserted collar 7 and a folded collar 12.After the rip strip is torn away the end 16 is provided with thisdepending folded collar which has a frictional slip connection with theouter wall of the collar 7. The end can be readily removed at any timeand replaced by slipping the col lar 12 down over the collar 7. Duringthe opening of the container there is no spilling of the contents as thetwo collars are in engagement with each other.

It will also be noted that the fold 13 extends well up in rear of thedouble seam, so that the pressure on the metal incident to the formingof the double sea-m does not in any way disturb the metal at the scoreline 10.

While there has been shown a specific form of inserted collar secured tothe body by spring locking lugs, it will be understood that other typesof inserted collars may be used as the present invention is directedparticu larly to the depending collar attached to the end which isreleased and the construction of the same.

It is obvious that minor changes in the details of construction and thearrangement of the parts may be made without departing from the spiritof the invention set forth in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. An easy opening container having score lines in the body walladjacent one end thereof thereby forming a rip strip, said body wallbeing folded upon itself so as to provide a depending portion adapted tocontact with the inner face of the body wall and said depending portionbeing folded upwardly upon itself and extending above said first namedfold in the body wall, so as to permit the upwardly extending portion tobe double seamed to the upper end of the container, and an insertedcollar located within the body portion, means for securing said insertedcollar to said body portion, the upper end of said inserted collaroverlapping and contacting with the lower portion of the dependingcollar formed by the folding of the body wall.

2. An easy opening container having score lines in the body walladjacent one end thereof forming a rip strip, said body wall beingfolded inwardly and downwardly upon itself so as to provide a dependingcollar extending below the upper score line, the said depending portionbeing folded upwardly upon itself and thence outwardly above the upperfold to provide a flange for seaming, an en having a depression thereinadapted to extend into the container body and an outwardly ex- 7 IALFRED L.
